Abstract
Svoveldioksydvaskeløsning som omfatter inhibitorer for oksydasjon av sulfitter til sulfater. Inhibitorene er kationiske polyelektrolytter som er vannloselige, har en molekylvekt på minst 10.000 dalton og inneholder kvaterhære amingrupper. Polyelektrolyttene er fortrinnsvis tilstede ved 1 til 3 000 ppm. i alkalilosninger, hvormed en svoveldioksydholdig gass-strom blir kontaktet.
